OIL FEED OR CHARGE DELIVERING DEVICE. I

Specification of Letters Patent.

Patented June 30, 1908.

Application filed August 22, 1906. Serial No. 331,653.

To all whom it may concern:

Be it known that I, JAMES E. KIMBLE, a citizen of the United States,residing at Vicksburg, in the county of Kalamazoo and State of Mlchigan,have invented certain new and useful Improvements in Oil Feed or OhargeDelivering Devices, of which the following is a specification.

This invention relates to improvements in oil feed or charge deliveringdevices.

My improved oil feed or charge delivering device is particularlydesigned for use as a lubricator, although it is very desirable for useas a liquid hydrocarbon feed device for explosion engines or the like.

The objects of this invention are, first, to provide an improved feeddevice of the class described adapted to deliver a fixed amount at eachcharge. Second, to )rovide an improved fecd device of the classdescribed,

Third, to provide an improved feed device of the class described whichis very simple in construction and very durable in use.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed. description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which Figure 1 is a side elevation of a structureembodying the features of my invention. Fig. 2 is an end elevationlooking from the left of Fig. 1. Fig. 3 is an enlarged horizontal detailsection, taken on a line corresponding to line 3 3 of Figs. 1 and 4.Fig. 4 is a detail vertical section taken on a line corresponding toline 4 4 of Fig. 3, showing structural details. Fig. 5 is an enlargedvertical section taken on a line corresponding to line 5 5 of Fig. 3,showing structural details. Fig. 6 is a detail view of the feed cylinderremoved from the cylinder chamber. Fig. 7 is a similar detail view of amodified construction having two charge pockets. Fig. 8 is a similardetail view of another modification having two charge pockets. Fig. 9 isa detail view showing a modification of the driving connection. Fig. 10is a side elevation showing another modification of the drivingconnection.

In the drawing the sectional views are taken looking in the direction ofthe little .ar-

rows at the ends of the section lines, and

similar letters of reference refer to similar parts throughout theseveral views.

Referring to the drawing, A is the oil recegtacle or reservoir, which ispreferably pro- Vl( ed with the base pieces A by means of' which it issecured in position. The reservoir is provided with a suitable cover, asA. In the bottom of the receptacle is a cylinder chamber a, the samebeing preferablyformed integral therewith. This cylinder chamber extendstransversely through the reservoir and is adapted to receive therevoluble feed cylinder. This feed cylinder preferably consists of ashaft B on which the sleevc-likc member B is arranged and secured,preferably by a pin, as 6, arranged thercthrough. On the outer end ofthe shaft B is mounted a ratchet segment C. A sleeve-like member B" ismovably mounted upon the shaft B. This sleeve is of the same diameter asthe sleeve B, both being adapted to revolubly fit within the cylinderchamber. The adjacent ends of the sleeves B B are cut away to form theextensions 1) 7) respectively, the extension of one member fitting intothe cut away portion of the other, the parts of the members beingshouldered together as clearly appears in the drawings and coact to formthe charge pocket, see Figs. 6, 7 and 8.

On the outer end of the sleeve B a ratchet segment 0 is mounted. Thesesegments are somewhat greater than half an arc and are arrangedoppositely so that they overlap, appears in Figs. 1 and 3. A bearing, asE, is provided for the cylinder, the bearing preferably being threadedinto the end of the cylinder chamber, as is illustrated. The cylindermembers B B are held in contact by the coiled spring 0. The coiledspring 0 is held in position by the threaded cylinder chamber cap E.(See Fig. 3.)

The segment C is preferably provided with an inwardly projecting hub con which the rock lever l) is mounted. On this rock lever D is the pawl(1, arranged to act upon the segments O and C. The pawl is provided witha spring (1 for holding it in engagement. The rock lever D is actuatedby the rod D or other suitable means.

With the parts in the position shown in the drawing, the actuation ofthe rock lever D acts upon the segment 0, revolving the shaft B untilthe charge pocket, which then opens into the discharge passage G, isclosed, at the same time opening the charge pocket on the opposite sideinto the inlet passage G. The continued movement revolves the cylinder Buntil the position of the pockets is reversed. The pawl then engages thesegment 0 of the member B, moving it upon the shaft B until it in turnengages the member B, which movement forces the charge into thedischarge passage G and opens the opposite pocket into the inlet passageG the pawl thus alternately acting upon the segments to alternatelyactuate the members B and B.

In order to insure the movement of the parts in proper relation to eachother, I provide the friction blocks F, one of which engages the memberB and the other the member B. These friction blocks are arranged insuitable holes bored into the wall of the cylinder chamber, and bearagainst the-sides of the members, as clearly appears in Fig. 3. Theblocks are held yieldingly in position by the coiled springs f. Thetension of these springs f is regulated by the threaded blocks F whichclose the outer ends of the holes.

The discharge passage G is connected by the tube G or otherwise to thepart to be lubricated, or to which the oil is to be delivered. It isevident that my-improved feed device delivers effectively againstpressure. As the charge pockets open in the inlet passage G, therebycreating a vacuum, they are positively filled at each stroke, so that aneven charge is insured, and this is true although the lubricant may bequite heavy or thick.

WVhere it is desired to deliver two or more charges at the same time,the ends of the members B B may be formed as is illustrated in Fig. 7,in which two pockets are shown. A further modification is shown in Fig.8, where a sleeve-like member B is interposed between the members B B.The ends of this sleeve are formed to coact with the members B B in thesame manner that they coact with each other in the structure of Fig. 1.In such a structure the charge pockets close successively, as will bereadily understood.

While I prefer to drive the charge cylinder by the rock lever shown inthe preferred construction, the same might be driven by means of thepulley c on the shaft 0, on

which is a pinion 0 arranged to mesh with the segments 0 and C.

In the modified form of the driving connection shown in Fig. 10, thegear H is provided with trips h for the double pawl I, so that thedevice is first actuated in one direction and then in the oppositedirection,

thereby opening the pocket in the inlet passages and closing it in theoutlet. The pawl I is supported on suitable pivoted bearings i on therock lever D. The pawl is held against one or the other stops on therock lever by means of spring K which is mounted on a pin j. This pin jis pivotally supported by the stud J. Other means of alternatelyimparting movement to the members of the feed cylinder will readilyappear to those skilled in the art to which this invention relates. Thefriction blocks also serve the purpose of holding the cylinderinposition, so that accurate fitting is not required and also thenecessity for packing removed. I thus accomplish in a simple manner theopening of the charge pockets in the reservoir and the closing of thesame in the discharge passage. As before stated, when the pockets areopened a vacuum is created so that they are positively filled.

While my improved feed device is particularly adapted for use as alubricator, it is desirable for use in other relations, as is heretoforestated. I have illustrated and described my-improved feed device indetail in the form preferred by me, although I am aware that it iscapable of considerable variation in structural details withoutdeparting from my invention.
